  INCIDENT DIAGNOSIS:
  .
  Drafting (GenDraft) / Wrong display of the Thread
  Line.
  .
  DEVELOPMENT REQUEST JUSTIFICATION:
  .
  The true problem here is the way threads are
  created. Tapered holes and screws are not a true
  geometry in the 3d design. It's just a data that
  figures on features ( holes or thread features).
  But the 3d geometry do not take it in account at all.
  To make appear those representations in the
  drawing, a temporary geometry is created on the
  fly during each view update. The problem with this
  geometry is that it makes a clash appear. Clashes
  are not officially supported by the
  projection engine. It is supported more or less
  depending on the situations. Here the thread trace
  (its projection) is just at the same depth than the
  border of the cut.
  .
  Depending on nearly nothing the trace is
  considered by the projection engine as seen or not.
  In the current state of the art it is impossible to do
  more without destabilizing other cases that
  are considered as more nominal.
  Answer and By-Pass
  As explained in the ppt provided in the materials
  the better by-pass is too move a bit the cutting
  body so as to avoid to get it exactly goes through
  the center axis of the hole.

  BYPASS:
